Specification of Letters Patent.

Patented June 9, 1908.

Application filed November 23, 1907. Serial No. 403,490.

'1 '0 all whom it may concern:

Be it known that I, GEORGE M. coma citizen of the United States, and residing in in the county of Allegheny and Stateof Pennsylvania, have invented or discovered new and useful Imrovements in Railway-Ties, of which the ollowing is a specificatiom y invention consists in new and useful improvements in metal railway ties. y process of, manufacturing the same consists in taking a sheet or plate of metal of stantially box form and forming circumferentially thereof a plurality I prefer to locate one of said circumferential corrugations at either side of the rail platform as illustrated in the drawings. Openlngs, as hereafter more fully described, are 4 provided in the top of the tie for the adjust- If desired, I may obtain the circumferential corrugations above referred to by first forming the same as transverse corrugations in the flat sheet which become circumferential corrugations when the sheet is bent up into box form.

' 'In the accompanying drawings, Figure 1 is a broken perspective of the original sheet or blank; Fi 2 is a broken perspective of the complete tie,- Fig. 3 is a partial longitudinal sectlon of the tie showin the rail secured in place, and Fig. 4 is abro en erspective of a modified form of the late, t e corrugations bein formed therein before bending up into 0x rm.

The following is a detailed description of my metal tie as the same is illustrated in the drawings.

I provide arolled or otherwise formed meta sheet 1 (Fig. 1) which is bent along the dotted lines a-a into a box form as shown in 2, the sides of the box being preferably tapered as shown and the two portions 2-2 which form the bottom of the box being preferably sli htly spaced apart to formthe slot 3. By t is means I provide a spring metal tie adaptedto assume the wave motion caused by traffic without fracture and without pounding the ballast. In the same operation by which the sheet 1 is bent u into the box form shown in Fig. 2 I form the circumferential corrugations 4-4, preferably located one on each side of the rail latform 5.' The corru ations serve to stiffen the tie against any attening tendency and also form a reinforced bearing for the fasten-- ing devices to be described.

The rail platforms 5-5 are provided with openings 6-6 extending preferably from corrugation to corrugation. 4-4 anr somewhat to the rear of each corrugation 4 is a bolt hole 7.

8 is the rail which rests on the rail platform 5 and 9-9 are fasteners whose up er portions engage the base, web and ball of the rail 8. The lower (portions of the fasteners 9-9 which exten through the aperture 6 are preferably substantially Z shaped whose arms 10-10 extend awayfrom the rail platform. Adjacent to the extremities of arms 1 0-10 are longitudinally slotted holes 11-11 which are located beneath the holes 7-7 in the tie top.

12-12 are bolts u through the holes 11-11 and 7-7 and held in place by nuts 13-13 screwed down on the tie top. I

14-14 are spring locking lates through which bolts 12-12 pass and w ose tongue 15 prevents the nuts 13-13 unscrewing.

The heads of the bolts 12-12 are rounded where they bear upon the under face of arms 10-10 so that a certain amount of play is permitted between the bolt and the fastener to assume the 'ar and thrust of traflic on the rails. The bolts 12-12 fit loosely in holes 7-7- so as to be rocked slightly without danger of fracture or being s prefer to outwardly and downwardly incline the upper parts of arms 10-10 so as to revent contact between the under side of the tieto and the fastener thus transmitting the fu l 'u ward tension of the'bolt into pressure of tlie fastener against the rail. apertures 6-6 and 7-7 are stamped out of the sheet 1 during t e process of bending the same u into box form.

If desired I may fi fst form the corrugations 4-4 in the sheet 1 (see Fig. 4) before the same is bent up into box form which corrugations then become circumferential corrugations as shown in Fig. 2.

- The tie made by this method is of very inexpensive manufacture. Moreover it, at the same time, possesses both strength enough to sustain the loads which are to be imposed and elasticity enough to safely assume the vibration and wave motion of traffic.

What I desire to claim is 1. As an article of manufacture, a railway tie consisting of a metal plate bent up into referably cared off. I

The a top thereof.

3. As an article ol manul'aetnre, a railway tie consisting of a metal plate bent up into substai'ltially box 'lorn'i with a eireumi'erential corrugation at either side of the rail platforms.

4. As an article of manul'aet'ure; a railway tie consisting of a metal plate bent up into substantially box form with a slotted bottom and having aeireunilerontial corrugation at either side of the rail platforms.

As an article of nuinulaeture. a railway tie consisting of a metal plate bent up into substantially box form with tapered sides and having eireunil'erential corrugations at either side ol the rail platforms.

(5. As an article of manufacture, a railway tie consisting of a metal plate. bent up into substantially box form with tapered sides and slotted. bottom, and having eireumferential corrugations at either side of the rail platform.
